КритикДень добрый, есть ли встроенное усечение строк, отличное от приведенного ниже?....

MSDN
Example
The following example normalizes a block of text string with unnormalized white spaces (tabs, leading and trailing spaces, and multiple spaces between words. The text string is the value of an <text> element.

XML File (normSpace.xml)

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl"
href="normalizeSpace.xsl"?>
<text>
This is a
test, with a lot of
irregular spacing and
waiting to be normalizaed.


</text>
XSLT File (normSpace.xsl)

<?xml version='1.0'?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="xml"
omit-xml-declaration="yes"/>

<xsl:template match="/text">
Unnormalized:
"<xsl:value-of select='.'/>"
Normalized: "<xsl:value-of select='normalize-space()'/>"
</xsl:template>

</xsl:stylesheet>
This XSLT produces the following output:

Unormalized:
"
This is a
test, with a lot of
irregular spacing and
waiting to be normalizaed.


"
Normalized:
"This is a test, with a lot of irregular spacing and waiting to be normalized."
