Answer 1

Instead of trying to edit files in place, wouldn't it be simpler to use the copy task as a templating system, it supports a filterset which can be used to substitute production values.
Example
.
├── build.xml
└── src
└── resources
└── persistence.xml
build.xml
<project name="demo" default="template">
<target name="template">
<copy todir="build/META-INF">
<fileset dir="src/resources" includes="*.xml"/>
<filterset>
<filter token="HIBERNATE.HBM2DDL.AUTO" value="create-drop"/>
</filterset>
</copy>
</target>
<target name="clean">
<delete dir="build"/>
</target>
</project>
persistence.xml
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
version="2.0">
<persistence-unit name="sample">
<jta-data-source>java:/DefaultDS</jta-data-source>
<properties>
<property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
<property name="hibernate.hbm2ddl.auto" value="#HIBERNATE.HBM2DDL.AUTO#"/>
</properties>
</persistence-unit>
</persistence>

That snippet works for me:
<?xml version="1.0" encoding="windows-1252" ?>
<project default="init" basedir=".">
<property file="build.properties"/>
<target name="init">
<tstamp/>
<loadfile property="jndiurl"
srcfile="${src.model}/META-INF/persistence.xml">
<filterchain>
<linecontains>
<contains value="hibernate.jndi.url"></contains>
</linecontains>
<headfilter lines="1"/>
</filterchain>
</loadfile>
<echo>${jndiurl}</echo>
<replace file="${src.model}/META-INF/persistence.xml" token="${jndiurl}"
value="${hibernate.jndi.url.live}${line.separator}"/>
<echo>${hibernate.jndi.url.live}</echo>
</project>
