Pattern matching throwing an Exception

sunnykeerthi · September 17th, 2014, 05:53 AM

I've the below 2 XML Files.

Title.XML

<?xml version="1.0" encoding="UTF-8"?>
<entry>
<file name="LCCPMY_CH_01.xml"></file>
</entry>
Contents.xml

Code:

<toc-pg>1</toc-pg>

and the content of LCCPMY_CH_01.xml is as below.

Code:

<chapter num="A">
    <section level="sect1">
    <page num="1"/>
        <title>
            <content-style font-style="bold">Chapter 1: This is Chapter</content-style>
        </title>
        </section>
</chapter>

here what i'm trying to do is from Content.xml file, by using the help of Title.xml file, i'm trying to match the number(page num of LCCPMY_CH_01.xml is equal to Contents.xml toc-pg value). I'm using the below XSLT to do it.

Code:

<xsl:template match="toc-pg" mode="x">
<xsl:variable name="dot" select="."/>
    <xsl:analyze-string select="." regex="([0-9]+)">
        <xsl:matching-substring>
            <xsl:variable name="prent">
                <xsl:for-each select="document('C:\Users\u0138039\Desktop\Proview\MY\2014\The Law of Costs in Civil Proceedings\title.xml')/entry/file">
                    <xsl:value-of select="normalize-space(document(concat('C:\Users\u0138039\Desktop\Proview\MY\2014\The Law of Costs in Civil Proceedings\',./@name))/chapter/section[@level='sect1']/substring-after(fn:substring-before(.,':'),' ')[//page/@num=$dot]|a[//page/@num=$dot])"/>
                </xsl:for-each>
            </xsl:variable>
            <xsl:variable name="cha">
                <xsl:value-of select="$prent"/>
            </xsl:variable>
            <xsl:variable name="size">
                <xsl:value-of select="string-length($cha)"/>
            </xsl:variable>
            <xsl:variable name="conct">
                <xsl:choose>
                    <xsl:when test="$size>'1'">
                        <xsl:value-of select="concat('er:#LCCPMY_CH_',$cha,'/pg_',.)"/>
                    </xsl:when>
                    <xsl:otherwise>
                        <xsl:value-of select="concat('er:#LCCPMY_CH_0',$cha,'/pg_',.)"/>
                    </xsl:otherwise>
                </xsl:choose>
            </xsl:variable>
            <a href="{$conct}">
                <xsl:value-of select="regex-group(1)"/>
            </a>
        </xsl:matching-substring>
        <xsl:non-matching-substring>
            <xsl:value-of select="."/>
        </xsl:non-matching-substring>
    </xsl:analyze-string>
</xsl:template>

but when i'm running this I'm getting the below Exception.

Code:

XSLT 2.0 Debugging Error: Error: file:///C:/Users/u0138039/Desktop/Proview/MY/2014/The%20Law%20of%20Costs%20in%20Civil%20Proceedings/09172014/XSLT/MCCL_TOC_01.xsl:235: Not a node item - item has type xs:string with value '1' -   Details: -     XPTY0020: The context item in an axis step must be a node
please let me know where am i going wrong and how can i fix this. I use XSLT 2.0.

The error is thrown here

Code:

<xsl:value-of select="normalize-space(document(concat('C:\Users\u0138039\Desktop\Proview\MY\20‌14\The Law of Costs in Civil Proceedings\',./@name))/chapter/section[@level='sect1']/substring-after(fn:subst‌ring-before(.,':'),' ')[//page/@num=.]|a[//page/@num=.])"/>

Thanks

where you do this:

Code:

substring-after(substring-before(.,':'),' ')[//page/@num=$dot]

the //page is being selected with the result of substring-after() as the context item; you can't select a node starting at a string. I think you are missing some parentheses somewhere.
