apply templates select substring-after - xslt-2.0

I've the below XML line.
<toc-title>1. <content-style>Short title</content-style></toc-title>
here i wanted to apply templates on substring-after 1.
I tried the below XSLT.
<xsl:template match="toc-title/text()" mode="x">
<xsl:analyze-string select="substring-after(.,' ')" regex="([a-z]+)">
<xsl:matching-substring>
<xsl:apply-templates select="regex-group(1)" mode="x"/>
</xsl:matching-substring>
<xsl:non-matching-substring>
<xsl:value-of select="."/>
</xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:template>
<xsl:template match="text()" mode="x">
</xsl:template>
but when i run this it throws the below error.
XSLT 2.0 Debugging Error: Error: file:///C:/Users/u0138039/Desktop/FLPHK_CHAP.xsl:239: Not a node item - item has type xs:string with value 'title' - Details: - XTTE0520: The result of evaluating the 'select' attribute of the <xsl:apply-templates> instruction may only contain nodes
I'm, unable to how to do this. please help me on fixing it.
Thanks

Conditional Formatting XSL

I'm trying to make <sup> elements superscripted when I encounter them. I'm iterating over a large file which I can include if required, basically <xml><article><body><p><em></em><sup></sup></p></body></article></xml>
I'm receiving:
Error reported by XML parser: The element type "fo:inline" must be terminated by
the matching end-tag "</fo:inline>"
when trying to use the below to raise the superscripts:
<xsl:for-each select="*">
<fo:block>
<xsl:if test="name() = 'sup'">
<fo:inline vertical-align='super' baseline-shift='4pt'>
</xsl:if>
<xsl:apply-templates select="." mode="xhtml"/>
<xsl:if test="name() = 'sup'">
</fo:inline>
</xsl:if>
</fo:block>
</xsl:for-each>
How can I correct this so the vertical-align='super' is only for sup elements; and is there a better approach to this? I plan to do the same for ems later.
My code which I use currently but puts everything out as plain text is:
<xsl:for-each select="*">
<fo:block><xsl:apply-templates select="." mode="xhtml"/></fo:block>
</xsl:for-each>
If you want to transform <sup></sup> to <fo:inline vertical-align='super' baseline-shift='4pt'></fo:inline> then the usual way with XSLT is to set up a template
<xsl:template match="sup">
<fo:inline vertical-align='super' baseline-shift='4pt'>
<xsl:apply-templates/>
</fo:inline>
</xsl:template>
I am not sure whether you want to do that in general or for a particular mode (in that case add mode="mode-name" on the xsl:template and mode="#current" on the xsl:apply-templates).

how to match the case sensitive characters in elements

I want to match the two or more case-sensitive characters in element of familName in author element. If found the ERROR message should be shown otherwise the familyName content will shown. The below code is not viewed in browser. Please check. I have used the xsl version is 2.0.
XML CODE
<author><familyName>CH</familyName> <givenNames>JC</givenNames></author>
XSLT CODE
<xsl:for-each select="author">
<xsl:choose>
<xsl:when test="matches(familyName,'([A-Z]){{1,}}')"><xsl:text>ERROR</xsl:text></xsl:when>
<xsl:otherwise>
<xsl:value-of select="familyName"/>
</xsl:otherwise>
</xsl:choose>
</xsl:for-each>
Its working for me. You can write a specific template for showing error:
<xsl:template match="familyName[matches(.,'^[A-Z][A-Z]+')]">
<xsl:text>ERROR</xsl:text>
</xsl:template>

pattern not matching though declared

I've the below XML.
<root>
<para>
<label>5.</label> In essence, the Court in <star.page>19</star.page>
</para>
<para>
<label><star.page>21</star.page> 13.</label> Frankly, I cannot see how
one can escape
</para>
</root>
and using the below XSLT.
<xsl:template match="para">
<xsl:apply-templates select="./node()[1][self::star.page]|./label/node()[1][self::star.page]" mode="first"/>
</xsl:template>
<xsl:template match="star.page" mode="first">
<xsl:if test="preceding::star.page">
<xsl:processing-instruction name="pb">
<xsl:text>label='</xsl:text>
<xsl:value-of select="."/>
<xsl:text>'</xsl:text>
<xsl:text>?</xsl:text>
</xsl:processing-instruction>
<a name="{concat('pg_',.)}"/>
</xsl:if>
</xsl:template>
here when i try to run this code, the first para star.page is getting caught, but the second star.page, i.e. <para><label><star.page>21</star.page> 13.</label>... is not getting caught. please let me know where am i going wrong. here i'm taking [1], since i want to catch the first occurance.
Thanks
I just tried your code on xmlplayground, both the star.page elements reach the template but the if clause is preventing the first from reaching the output.

XSLT 2 - pick item from tokenize()'d list by index

My environment is SAXON (last nights build) using XSLT 2.0. My real problem is that the XML document specification is sub-optimal, and in a way, my problem relates to fixing/working around that design issue.
I have a node type (<weaponmodesdata>) where all the direct children are |-separated string lists of 1-or-many elements (each child of the same <weaponmodesdata> will have the same length). I need to go over the various modes represented and "unspin" them out to separate item lists (in plain text), rather than having them all smooshed together.
Unfortunately right now I'm getting a really stubborn
XPTY0020: Required item type of the context item for the child axis is node(); supplied
value has item type xs:string
error on the lines where I pass the node that needs to be split up into my little template.
Currently I have
<xsl:template match="trait" mode="attack">
<xsl:for-each select="tokenize(weaponmodesdata/mode, '\|')">
<xsl:variable name="count" select="position()"/>
<xsl:value-of select="name"/><xsl:text> - </xsl:text>
<xsl:call-template name="split_weaponmode">
<xsl:with-param name="source" select="weaponmodesdata/damage"/>
<xsl:with-param name="item" select="$count"/>
</xsl:call-template>
<xsl:text> </xsl:text>
<xsl:call-template name="split_weaponmode">
<xsl:with-param name="source" select="weaponmodesdata/damtype"/>
<xsl:with-param name="item" select="$count"/>
</xsl:call-template>
<!-- more will go here eventually -->
<xsl:text>.
</xsl:text>
</xsl:for-each>
</xsl:template>
<xsl:template name="split_weaponmode">
<xsl:param name="source"/>
<xsl:param name="item"/>
<xsl:variable name="parts" select="tokenize($source, '\|')"/>
<xsl:for-each select="$parts">
<xsl:if test="position() = $item">
<xsl:value-of select="."/>
</xsl:if>
</xsl:for-each>
</xsl:template>
An example XML subtree relating to my issue:
<character>
<trait id="1">
<name>Spear</name>
<weaponmodesdata>
<mode>1H Thrust|2H Thrust|Thrown</mode>
<damage>thr+2|thr+3|thr+3</damage>
<damtype>imp|imp|imp</damtype>
</weaponmodesdata>
</trait>
<trait id="2">
<name>Broadsword</name>
<weaponmodesdata>
<mode>1H Thrust|1H Swing</mode>
<damage>thr+1|sw+2</damage>
<damtype>imp|cut</damtype>
</weaponmodesdata>
</trait>
</character>
Example desired output:
Spear - 1H Thrust; thr+2 imp.
Spear - 2H Thrust; thr+3 imp.
Spear - Thrown; thr+3 imp.
Broadsword - 1H Thrust; thr+1 imp.
Broadsword - 1H Swing; sw+2 cut.
One issue (that one causing the error message) with your code is that your for-each operates on a sequence of string value (i.e. inside the for-each body the context item is a string value), yet you have relative XPath expressions like weaponmodesdata/damage that require a context node to makes sense. So you would need to use a variable outside of the for-each to store your context node.
But I think you can simplify your code to
<xsl:stylesheet
version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs">
<xsl:output method="text"/>
<xsl:strip-space elements="*"/>
<xsl:template match="trait">
<xsl:variable name="this" select="."/>
<xsl:variable name="count" select="count(tokenize(weaponmodesdata/*[1], '\|'))"/>
<xsl:for-each-group select="weaponmodesdata/*/tokenize(., '\|')" group-by="position() mod $count">
<xsl:value-of select="$this/name"/>
<xsl:text> - </xsl:text>
<xsl:value-of select="current-group()"/>
<xsl:text>.
</xsl:text>
</xsl:for-each-group>
</xsl:template>
</xsl:stylesheet>
If you want to stick with your approach of calling templates then make sure you store the context node of the template using e.g. <xsl:variable name="this" select="."/> so that you can access it inside of the for-each iterating over a string item.

Eliminate line-breaks with XSLT 2.0 analyze-string

I use the XSLT 2.0 element analyze-string in a stylesheet that transforms XML to HTML; specifically, I use it to convert string encoding for subscripts in chemical formulae to HTML subscripts. Therefore, the result is a string, to go in a p or td element, with embedded mark-up.
The transformation is supposed to produce output like H2O but in fact inserts a line-break in the HTML:
H
<sub>2</sub>O
and this break is (correctly) interpreted by the browser as a space:
H
2O
which is ugly.
Is there a way to remove the line-break? I've tried putting the whole analyze-string element on one line and that doesn't work.
The input would be something like
<OrdinaryStructralFormula>H$_2$O</OrdinaryStructuralFormula>
for a simple case and
<OrdinaryStructralFormula>C$_2$OH$_5$$^-</OrdinaryStructuralFormula>
for a more-complicated one. Note that the subscript pattern can match multiple times in the general case and can be either in the middle or at the end of the string. The pattern also has to match and eliminate any notation for charge: the $^- bit at the end of the second example.
The XSLT processor is Saxon 9.4 and the XSLT template follows.
<xsl:template name="formula">
<xsl:param name="formula"/>
<xsl:if test="$formula">
<xsl:variable name="f" select="translate($formula, '$', '')"/>
<xsl:analyze-string select="$f" regex="(_)(\d+)|(\^)\d*\+|(\^)\d*\-">
<xsl:matching-substring>
<xsl:if test="regex-group(1)='_'">
<sub><xsl:value-of select="regex-group(2)"/></sub>
</xsl:if>
</xsl:matching-substring>
<xsl:non-matching-substring>
<xsl:value-of select="."/>
</xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:if>
</xsl:template>
I cannot reproduce the reported result.
This transformation (which is what you should have given us, but you only provided a template):
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/">
<xsl:call-template name="formula">
<xsl:with-param name="formula" select="/*"/>
</xsl:call-template>
</xsl:template>
<xsl:template name="formula">
<xsl:param name="formula"/>
<xsl:if test="$formula">
<xsl:variable name="f" select="translate($formula, '$', '')"/>
<xsl:analyze-string select="$f" regex="(_)(\d+)|(\^)\d*\+|(\^)\d*\-">
<xsl:matching-substring>
<xsl:if test="regex-group(1)='_'">
<sub><xsl:value-of select="regex-group(2)"/></sub>
</xsl:if>
</xsl:matching-substring>
<xsl:non-matching-substring>
<xsl:value-of select="."/>
</xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:if>
</xsl:template>
</xsl:stylesheet>
when applied on the following XML document with Saxon 9.1.05:
<formula>H$_2$O</formula>
produces the wanted, correct result:
H<sub>2</sub>O
When the same transformation is applied on the second XML document:
<OrdinaryStructuralFormula>C$_2$OH$_5$$^-</OrdinaryStructuralFormula>
Again the wanted correct result is produced:
C<sub>2</sub>OH<sub>5</sub>
Do note: I ran the same transformations with two other XSLT 2.0 processors: XQSharp (XMLPrime) and AltovaXML (XML-SPY) and got exactly the same, correct results.
