Ist is not well-formed your Input plz check
if you want only text change then use this code with replace function:
Input:
<?xml version="1.0" encoding="UTF-8"?>
<p type="TOC_Level Two Entry">
<tps:doclink refType="anchor" refId="fig-FigF.3A" xmlns:tps="htttp:\\tps">Figure F.3A—Text<tps:c type="TOC_Leader Dots"><t/></tps:c></tps:doclink>
<ref format="TOC Page Number" refType="anchor" refId="fig-FigF.3A"/>
</p>
code:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="xs"
version="2.0">
<xsl:output method="xml" omit-xml-declaration="no"/>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="text()">
<xsl:value-of select="replace(., '(Figure )([A-Z])([.])([0-9A-Z]+)(.+?)([A-Za-z]+)', '$2$3$4')"/>
</xsl:template>
</xsl:stylesheet>
output:
<?xml version="1.0" encoding="UTF-8"?>
<p type="TOC_Level Two Entry">
<tps:doclink xmlns:tps="htttp:\\tps" refType="anchor" refId="fig-FigF.3A">F.3B<tps:c type="TOC_Leader Dots"><t/></tps:c></tps:doclink>
<ref format="TOC Page Number" refType="anchor" refId="fig-FigF.3A"/>
</p>

Answer 2

So, trying to extract a clear requirements statement from this, it seems you want the input "fig-FigF.3A" to result in the output "F.3A". Alternatively, perhaps you want to treat "Figure F.3A—Text" as the input? On the one hand you say you are selecting the #reId attribute -- which doesn't exist in your input; on the other hand your attempt at a solution is looking for the text "Figure" which appears in a text node, rather than an attribute.
So I think we need a much clearer requirements statement.
The other problem with this as a requirements statement is that you only really give one example, not a general rule. There's a hint of a general rule in your question "which has a character after a digit". But what does this mean? Your example seems to be looking for the pattern letter-dot-digit, which doesn't match your description of the problem at all.
Sorry, SO moderators, this isn't an answer, it's a comment on the question. It started as an answer, until I realised the question wasn't clear, but by then it was too long for a comment.
